to wat i tink, the higher the compressor btu, the time taken to cool the room would be faster, thus wil also reach the desired temperature at a shorter time. the time on full load wil also be shorter.

but than do remember tat the total compressor btu is added up together as there r "2 compressor" (TWIN) inside.

hi chunliang;

may i know the model of yr compressor & FCU x 2 units? what is the cost of the system and its configuration? such as armaflex insulation or G22 totaline piping ....

i was quoted for the model;

RAS-3M20SACV/RAS-M10SKCV+RAS-M13SKCV for $2470 and new bracket $150. this cost is without the change of copper pipe or insulation.

do you think is over...
thanks

no matter how the piping goes up or down, u do not hav to worry.

as the height limit between the compressor n fcu is within the max height difference as stated in the outdoor unit specification.

condensation wil take place when there is a big gap between outer diameter of copper pipe n inner diameter of insulation. i believe every installer knw this, so this should not happen anyway.
So there is no problem with my installation? Thanks for your help.

If u bought @ Fairprice, contractor Trend Homes will do the installation.
$2,799 is around market price.

hi chunliang;
tks for yr response. the price gap is quite wide comparing betw inverter or not. in addition, the quote was for system 2 while yrs for system 4.

cheers

Hello,

I hope my post is not out of place in this thread.

The air con in my house is split unit and the pipes are encased inside PVC casing. Recently, I notice hte PVC casing leaking water. I think the pipes inside the casing are freezing so when it defreezes, the water leaks.

Is this true? How can I go about solving this problem? Thanks

is it mean the higher the number, the better the performance n efficiency?
performance in terms of efficiency, yes.

the higher the COP, the more efficient would be the air-con.

happened to me once... dunno if it's the same problem but watch out when you open the trunking (PVC casing). There might be a fair bit of accumulated water inside!

in my case, it was sweating (condensation) on the drainage pipe led to water being accumulated inside the trunkings. while my cu pipes are insulated properly, the drainage pipe was insulated with a thin normal insulator. GC came bck and gave my drainage pipes a thick armaflex insulation. So far so good...

my suggestion is call your contractor to access the problem. i dun think it's something you can fix it on your own.

also, what temp/fan setting are you using?

try to increase both temp (i.e. less cool) and fan speed. that way at least your return gas would not be as cold... if your problem is due to condensation, this might lessen it but it would not solve it.

I dun have photos of the toilet internal now coz i forgot to take perhaps the next time i went down again then i took the internal. I worry coz ppl say usually their trunking running below their unit not above the unit.
no lah... usually the trunkings run below the FCU becoz the drainage pipe and the refridgerant gas pipes are housed in the same trunkings.

and since the drainage pipes must go downwards (even so, not necessary... some use pump! but uncommon lah), so must the trunkings.

hey! we're using the same brand.

the problem might be tat there is a big gap between the outer diameter of copper pipe n inner diameter of insulation, in this case it wil cos condensation. n another thing is tat when they join the insulation, they nv tape properly, tats y air goes in which creates condensation.

if the installer use the correct diameter, shld not hav any problem.

so doing it on yr own is possible, but u got to knw wat u doing.

Hi All,

Thanks for the info rendered! So I think my problem here is the condensation.

So will this condensation lead to some electric shock thus leading to a short ciruit of the electricity flow in the house? (sorry sounding abit paranoid here , just wanna ensure coz I'm no electricity expert. )

So this problem is not dangerous?

So u also installed by Gain City? What insulation u using? Any problems with their insulation? I feel worried coz the guys like doing things anyhow. A bit worried.
